' TACK-HANDLING MECHANISM.

Original application filed August 22, 1917, Serial No. 187,594, which has matured into Patent No.

1,530,349, granted March 1'7, 1925.- 9,324.

This invent-ion relates to tack handling mechanism and particularly to tack separating mechanism, this application beinga division of our application SerialNo. 187,59 l, filed August 22, 1917, which has matured into United States Letters Patent No. 1,530,- 349, granted March 17, 1925. The invention is herein shown for the purpose of exemplification as embodied in a tack separating mechanism for a lasting machine such as that disclosed in United States Letters Patent No. 1,007,051, granted October 81, 1911, on application of Arthur Bates, as wellas in our said prior application, such machines being equipped to separate and insert two tacks in each cycle of the machine.

An object of this invention is to provide an improved and simplified tack separating mechanism adapted for such machines, although the inventionis not limited to such application.

A feature of the invention consists in an organization having a-plurality of tack raceways, a plurality of conduits to which tacks are to be delivered, and a tack separator having a single tack separating portion constructed and arranged to separate a tack from each raceway successively and to deliver the separated tacks to the tack conduits.

! As shown herein,'the separator comprises a reciprocating blade having a tack separating finger and a curved slot by which the "tack, after being separated bythe finger, is moved outwardly of the raceway and transferred into position over the tack conduit, the slot being enlarged at its inner end to permit the head of the tack to drop through the separator blade. After separation of the tack fromithe first raceway, the movement of the tack finger continues and a tack is separated from another raceway and transferred by the same into position over another conduit. The enlargement of the slot is preferably extended in the direction of movement of the separator blade and as herein shown leaves themouths or" bothconduits uncovered when the separator is at the end of its separating movement. By this extension of the slot rapid movement of the separator is per- Divided and this application filed February 14, 1925. Serial No.

mitted without danger of the end-of the slot interfering with the passage of the tacks to their respective conduits.

In the drawings,

Fig. 1 is a side view of a portion of the head of a hand method lasting machine embodying the present invention;

Fig. 2 is a plan view showing the tack separating mechanism; and

Fig. 3 is a front elevation of a rating mechanism.

The machine in which the present invention is shown as embodied for the purpose of explanation is provided with ashoe rest 2 against whichthe bottom ofa shoe is held by the operator, an edge gage 4 to determine the lateral position of the shoe, a gripper 6 for working the upper into lasted position,

tack sepaa combined tack block and wiper 8 which is reciprocated to wipe the lasted upper over the shoe bottom, and drivers 10 by which the tacks presented under it by the tack block are driven into the shoe.

Mounted in a convenient posit-ion on the head of the machine are .two raceways 12, 14, which may be of usual construction, for feeding tacks toward the separator. EX- tending across the open end portions of the raceways 12,14 is a separator block 16 (Fig. having downwardlyextending openings or conduits 18 for the passage of separated tacks toward the tack carrier, that is, the combined tack I block and wiper 8. The downwardly extending passages or conduits 18 have open side portions in alinement with the open end portions of .the-raceways 12, let.

Such passages preferably diverge downwardly, as indicated in F ig. 3, so that as the tacks delivered to the passages pass downwardly to thetack carrier they will be separated as determined by the divergent-arrangementof the passages.

Mounted for reciprocating movement in the separator block 16 is a tack separator slide 20 having a 7 single tack separating passage or slot 22 and an opening 24 formed as an enlargement of the slOt 22 extended in the direction ofmovement of the separator slide and adaptedto receiveand-permit the passage of the tacks, one to each of the conduits 18, the construction being such that as the separator slide 20 is reciproca'ted past the end portions ot the raceways 12 the single separating slot 2). will detach the end-most tack from each raceway and cam or move it outwardly as the slide moves to the let't (Fig. 3) so that the tacks thus separated will Ilrop into the passages 18 and pass dowmvzu'dly into the tack carrier 8 when that element is in tack receiving po sition. The extension of the slot opening 24L allows the separator to be moved rapidly without danger of the end of the slot engaging the tack lirst separated and interitering with its passage into the proper con duit. The tack carrier slide (Fig. 2) is provided with a series of rack teeth 26 (Fig. 2) which are'engaged by the teeth of a segment 28 carried by one arm of a lever 30 pivoted at 32 and connected at Set to lever actuating means. This actuating means may comprise connections to a wiper carrying slide 36 so that as the slide reciprocates motion will be in'iparted to the lever 30 and preferably this motion is imparted yieldingly in both directions so tl'iat, should the movement of the slide be obstructed. by a bent tack or other cause, no

parts of the machine will bev broken or in-' jured.- To etl'ect this yielding connection, as shown, themain slide 36 which carries the wiper 8 is mounted for to and tro reciprocating movement. and carries a hollow bar 38 having a slot'through which passes a supporting pin l2 extending from the frame of the machine. Through'the other end portion of the bar 38 extends a stud or pin 4A which connects the bar for movement with the slide 36. The bar 38 is proconstruction being such. that should. the tack separator be obstructed in its movemcntiu either direction, one or the other ot the springs 48 or 54L will yield, thereby preventingbreakage of parts. I

Between the upper and. lower ends ol the tack carrying openings 5c are arranged tack sustaining springs 58 to hold. the tacks in the passages until they are carried by movement of the wiper to driving position and are forced through the passages by descent of the drivers 10 into the work beneath the wiper.

essors Having thus described the invention, what we claim as new and desire to secure by Letters Patent of the United States is:
